Sorry to bring this back up, but I wanted to warn people of my experience here:
The Ram Man, Inc. 1999-2006 Jeep Wrangler 4X4 Unit Bearing Locking Hub Kit, SKU 000345, $1,795.
http://therammaninc.com/products/sh...WRANGLER-4X4-UNIT-BEARING-LOCKING-HUB-KIT-345
I ordered The Ram Man Inc locking hubs to report on them and do a review. I told him that I was excited about buying the parts, and that I would do a review on my TJ forum.
I have read this whole thread multiple times, and considered everything carefully. Just as a re-cap I have a 89 Jeep TJ with a Ford 8.8 rear and standard Dana 30 front. I re-geared to 4:88's, and I have the famous vibration at 60. I didn't diagnose anything for sure, so I am not saying that my front end is exactly the problem, but I thought either way locking hubs would be a great way to disconnect the front end regardless of the vibration.
I considered the ones that
@Mr. Bills did, but that would change the lug pattern, Not a huge deal, but then I would have to change the rear axles too or run spacers in the rear, and buy new wheels. That equaled to a lot more money and more maintenance in the end. Also the Ram Man is actually 300 dollars cheaper now then when this post was originally made. I also considered the cheaper Yukon's because it wouldn't change the pattern, but would extend the front end 3/4 inch which is bad because the rear is slightly narrower than the front before I even start this project. Again I could run spacers in the back, but really not wanting to do that.
I looked at the Spintec(sp) as well, but their customer services was not great just trying to get information was like pulling teeth.
I liked the idea of the RAM man hubs because they used the factory bearings with some custom work, and nobody here that I know have has tried them, so I thought I would take one for the team and then report on them.
So while I was in Moab in the beginning of May, I started a Dialog with him, and what I presume is his wife. They answered all of my questions via email and replied within a few days each time. They sent videos, and I was getting really pumped for these. I thought I found a locking hub buddy. Then the day I got back from my Moab adventure I ordered a set for my TJ. I was pretty stoked!
Then after a few weeks of nothing, I emailed and got no response for a few days, then I called and called and called, never did they answer their phone. Not even once. Then I finally got an email saying that they would be shipped out the next week, so I waited and waited. Finally, not sure what to do, I tried to google the Ram man, and I am finding this everywhere. Parts never show up, can't get a hold of him. Doesn't honor warranties etc. So I checked BBB and found that someone filed a claim on there that sounded a lot like mine.
I filed a charge back with my bank and it was a huge hassle. My friends have been telling me that it usually isn't that much of a hassle, but I use a Credit Union from another state, and their Visa card is not in house so it was kind of a nightmare. Luckily for me the Ram Man makes you pay with PayPal so I paid with my credit card through PayPal, and they actually took care of me. It wasn't as easy as people make you think, but it worked. It was ruled in my favor, and I have been out 1495.00 for over a month and a half, and could take another month to get my money back. At least I know at some point I will get my refund.
I have been hesitant to buy new parts till I found out how this was going to end, but now I think I am going to properly diagnose my TJ before just putting hubs on to fix my vibration issues which may or may not be the front end. I still want locking hubs, but I may not need them right away. I am going to do things like pull the front drive line replace my broken trans mount, and rotate the tires and see what that nets me. After all of that if I still have the vibes. I may just go ahead and do what
@Mr. Bills did with the exception of adding a c-clip eliminator in the rear so match the new lug pattern. A c-clip eliminator will extend my rear diff a 1/2 inch each side so it should level out the diff sizes in the end too.
My advice is to stay far away from TheRamManInc.com.
